MMH
===


`MMH <http://www.astronautix.com/m/mmh.html>`_ or Monomethylhydrazine (CH3NHNH2) 
is a storable liquid fuel that found favor in the United States for use in 
orbital spacecraft engines. Its advantages in comparison to 
`UDMH <http://www.astronautix.com/u/udmh.html>`_
are higher density and slightly higher performance.
